electrodermal activity (EDA)
SCL
SCR

Facial Electromyography (EMG)
corrugator muscle

And you should be able to answer these questions after reading Potter & Bolls Chapter 5:

1. What's the difference between the way psychologists understand the terms emotion, mood, and attitude?

2. Why in the world would you ever put an EDA sensor on a research subject's foot?

3. One of the major differences in measuring EDA and EMG is where the electrical signal originates. Describe that difference.

4. Why do you want to make sure that you don't put too much electrolyte gel into the small EMG electrodes? What does this have to do with the concept of bipolar measures?
